SpringSecurityのDB認証，WebSecurityConfigでの引数エラー

前提・実現したいこと

Spring Security初学者です．
DBからユーザ情報を取得し，認証を行う処理を実装したいのですが，以下のエラーメッセージが発生しました。

発生している問題・エラーメッセージ

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'webSecurityConfig': Injection of autowired dependencies failed; nested exception is java.lang.Error: Unresolved compilation problem:
        The method userDetailsService(T) in the type AuthenticationManagerBuilder is not applicable for the arguments (UserDetailsService)

WebSecurityConfigのUserDetailsServiceを指定する際に，型の不整合が発生してしまい，お手上げの状況です．
